Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, specifically to a bag conveying device for an automatic bag cutting and sewing machine. Background Technology

[0002] The automatic bag-making and sewing machine integrates three major functions: air cutting, bag making, and bottom sewing, enabling automated production of woven bags. Its workflow includes complex processes such as outer bag unwinding, automatic correction, and cutting, as well as inner film unwinding, heat sealing, and cutting. Specifically, the machine uses a cutting blade at the bottom of the slide to cut excess seams on the sides of the outer bag, and then uses the suction cups to pull up and open to adhere and fit the inner film, achieving rapid bag making of both the inner and outer bags.

[0003] As disclosed in the authorization announcement number CN115783633B, a bag conveying device is used to convey bags. It includes a conveyor, which includes a conveying chain and a motor for driving the conveying chain to move. It also includes a support plate, a support member, a drive assembly, and a pressing assembly.

[0004] Although it is equipped with a carrier, a drive component, and a pressing component, the bag is placed on the carrier, and the carrier is conveyed by the conveyor. The drive component gradually drives the pressing component to press the bag onto the carrier, so that the vibration generated by the conveyor during the conveying will not cause the bag placed on the carrier to fall off the carrier. This makes it easier for the conveyed bag to cooperate with the subsequent bag feeding device, and also avoids the problem of the bag getting stuck inside the conveying device and causing damage to the conveying device structure.

[0005] However, this does not solve the problem that existing conveying devices of this type are generally not conducive to the convenient and rapid conveying of bags from automatic sewing machines. They are not convenient for the conveying device to stably convey bags from automatic sewing machines in multiple directions, and it is not convenient to stop conveying bags from automatic sewing machines midway. This affects the range of bag conveying for automatic sewing machines and the efficiency of the conveying device in conveying bags from automatic sewing machines. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are: the conveying device not only realizes the convenient and fast conveying of the bag body of the automatic sleeve cutting machine, and facilitates the stable conveying of the bag body of the automatic sleeve cutting machine in multiple directions, but also facilitates stopping the conveying of the bag body of the automatic sleeve cutting machine in the middle, increases the conveying range of the bag body of the automatic sleeve cutting machine, and improves the conveying efficiency of the conveying device for the bag body of the automatic sleeve cutting machine.

[0016] (1) When the first electric roller drives the bag body of the automatic sleeve cutting machine to one side of the second electric roller, the lifting cylinder drives the belt to move to the same height as the first electric roller. The first electric roller then transports the bag body of the automatic sleeve cutting machine to the surface of the belt. The dual-axis motor drives the belt to move, and the belt drives the bag body of the automatic sleeve cutting machine to the surface of the discharge conveyor. The discharge conveyor opens to transport the bag body of the automatic sleeve cutting machine to the next process, so as to facilitate the convenient transport of the bag body of the automatic sleeve cutting machine. When it is necessary to transport to different positions, the bag body of the automatic sleeve cutting machine is transported to the surface of the belt. At this time, the lifting cylinder is opened in reverse, and the belt is lowered to the lowest position. At this time, the second electric roller supports the bag body of the automatic sleeve cutting machine. The second electric roller transports the bag body of the automatic sleeve cutting machine to one of the surfaces of the two sets of side conveyor frames. The side conveyor frames are opened to transport the bag body of the automatic sleeve cutting machine to the next process, so as to facilitate the automatic sleeve cutting machine to process the bag body. This realizes the convenient and fast transport of the bag body of the automatic sleeve cutting machine by the conveying device, and facilitates the stable transport of the bag body of the automatic sleeve cutting machine in multiple directions by the conveying device, increasing the range of bag body transport of the automatic sleeve cutting machine.

[0017] (2) The lifting cylinder drives the lifting plate to move through the lifting push rod. The limit rod provides sliding support for the lifting plate to facilitate the movement of the support beam, dual-axis motor, and belt to the appropriate position. The dual-axis motor drives two sets of rotating pulleys to rotate. The rotating pulleys drive the belt to move. Under the active support of the limit wheel, driven pulley, and support wheel, the belt stably conveys the bag body of the automatic sewing machine to prevent the bag body of the automatic sewing machine from being too heavy and causing pressure damage to the belt. This realizes the reliable and stable conveying of the bag body of the automatic sewing machine by the conveying device, increases the structural connection strength during conveying, and improves the efficiency of the conveying device in conveying the bag body of the automatic sewing machine.

[0018] (3) The power cylinder drives the moving plate to move through the power push rod. The support rod provides sliding support for the moving plate. The moving plate drives the moving block to move. The moving block lifts the bag body of the automatic sewing machine, so that the conveying device can conveniently brake the bag body of the automatic sewing machine. This realizes that the conveying device can conveniently and quickly brake the bag body of the automatic sewing machine, which makes it convenient to stop the conveying of the bag body of the automatic sewing machine in the middle and improves the practicality of the conveying device in operation.
